are there any recalls on 2007 Yukon denali transmission?

I would suggest calling the Dealer with your vin number (serial number). It is found on your registration card, on drivers door jam or at bottom of front windshield. They can tell you without going to the dealer if any recalls have been issued. The vin number is 17 digits and letters long. A recall is usually repair at the dealer under warranty at no cost. Good Luck!
